6.6.8 Showing/Hiding PI
You can set whether to display PI in the SpO
2
parameter area. To do so, follow this
procedure:
1. In Continuous Monitoring mode, select the SpO
2
numeric area or waveform area
to enter the SpO2 dialog. In Spot Check mode, select the Main Menu quick key
→ from the Parameters column select Setup → select SpO2.
2. Select the Setup tab.
3. Switch on or off Display PI.
NOTE
• This function is only available for Masimo SpO
2
.
6.6.9 Monitoring SpO
2
and NIBP Simultaneously
When monitoring SpO
2
and NIBP on the same limb simultaneously, you can switch on
NIBP Simul to lock the SpO
2
alarm status until the NIBP measurement ends. If you
switch off NIBP Simul, low perfusion caused by NIBP measurement may lead to
inaccurate SpO
2
readings and therefore cause false physiological alarms.
In Continuous Monitoring mode, you can set the NIBP Simul. Follow this procedure:
1. Select the SpO
2
numeric area or waveform area to enter the SpO2 dialog.
2. Select the Alarm tab.
3. Set NIBP Simul.
6.6.10 Changing the Sweep Speed of the Pleth Wave
To set the sweep speed of Pleth waveforms, follow this procedure:
1. In Continuous Monitoring mode, select the SpO
2
numeric area or waveform area
to enter the SpO2 dialog. In Spot Check mode, select the Main Menu quick key
→ from the Parameters column select Setup → select SpO2.
2. Select the Setup tab.
3. Set Speed.

6.8 Nellcor Information
Nellcor Patents
This posting serves as notice under 35 U.S.C.§287(a) for Covidien patents: http://

Problem Solution
Do not see SpO
2
numeric area or
waveform area on
the main screen
Check that the SpO
2
is set to display in the Edit Workflow menu.
For more information, see 3.9.1.2 Setting the Screen Layout.
Dashes “- -” display in
place of numerics.
1. Check that the cable connections of SpO
2
sensor and the
extension cable are tight. Replace the SpO
2
sensor or the
extension cable if needed.
2. Reconnect the SpO
2
sensor if the alarm SpO2 Sensor Off
appears.
3. Check the PI value. If the PI value is too low, adjust the SpO
2
sensor, or apply the sensor to the site with better perfusion.
4. Move the sensor to a place with weaker ambient light, or cover
the sensor to minimize the ambient light if the alarm SpO2
Excess Light appears.
Low amplitude SpO
2
signal
1. The SpO
2
sensor and NIBP cuff are placed on the same limb.
Change a monitoring site if necessary.
2. Check the PI value. If the PI value is too low. Adjust the SpO
2
sensor, or apply the sensor to the site with better perfusion.
3. Check the sensor and its application site.
SpO
2
value is
inaccurate
1. Check the patient’s vital signs.
2. Check for conditions that may cause inaccurate SpO
2
readings.
For more information, see 6.3 SpO
2
Measurement Limitations.
3. Check the monitor, the SpO
2
sensor for proper functioning.
